本文将弦理论的一种新方法应用于实际金融市场。它是文献[1]在价格预测中的直接推广和应用。该模型采用基于字符串不变量的预测模型(PMBSI)的思想构造。在人工时间序列和金融时间序列上，将PMBSI与支持向量机(SVM)和人工神经网络(ANN)的性能进行了比较。给出了结果和分析的简要概述。第一个模型是基于相关函数作为不变量，第二个模型是基于对闭合字符串/模式形式(PMBCS)的偏差的应用。我们发现了这两种方法之间的区别。与第二个模型相比，第一个模型不能以较好的效率预测外汇市场的行为，并且能够每年获得相应的利润。

英文摘要：
In this paper we apply a new approach of the string theory to the real financial market. It is direct extension and application of the work [1] into prediction of prices. The models are constructed with an idea of prediction models based on the string invariants (PMBSI). The performance of PMBSI is compared to support vector machines (SVM) and artificial neural networks (ANN) on an artificial and a financial time series. Brief overview of the results and analysis is given. The first model is based on the correlation function as invariant and the second one is an application based on the deviations from the closed string/pattern form (PMBCS). We found the difference between these two approaches. The first model cannot predict the behavior of the forex market with good efficiency in comparison with the second one which is, in addition, able to make relevant profit per year.
